    Subject[RFC PATCH 2/2] mtd: devices: m25p80: Enable spi-nor bounce buffer support
    Date
    Many SPI controller drivers use DMA to read/write from m25p80 compatible
    flashes. Therefore enable bounce buffers support provided by spi-nor
    framework to take care of handling vmalloc'd buffers which may not be
    DMA'able.
